Looking for blueprint for Santa Fe style Von Bodon burner used on the larger engines.

You'll get a lot further if you spell it correctly in search: von Boden - Ingles.

I have a little different version in an ICS "Oil Burning Locomotives" booklet. If you need a copy, please PM me a mailing address.

I have a 1951 SP report on oil burning. In a cursory check I found photos of seven variations of the type. There may be a drawing. Send me an email address.

Wouldn't the ATSF collection at the de Golyer library have the actual ATSF blueprints for these burners as installed in different classes? At one time there was a finding aid, or a digitized collection of material, available on CD or DVD...

I believe AT&SF used mostly Booth and Baldwin burners in their locomotive which was another drooling type of burner usually without a bottom lip extension. Almost all drooling type oil burners used an atomizer steam slot with a 1/32" space x width size of burner which ran from 1" to usually 4" wide as was the oil slot width. SP 4-8-8-2 only use a Von Bodon 3 1/2" burner.
But some TN&O locomotives use 4" burners.
in the late 1940s and early 1950s SP did extinctive stationary oil burner/firepan test using a GS1 in a building at Sacramento tests use over 6000# of fuel per hour. All work was trying to better mix the air with the fuel which required high turbulence air flow which required smaller exhaust nozzles which increase exhaust back pressure make locomotive less efficient. Out of all the research and testing SP developed the internal mix Gyrojet burner and new designed firepan, which was made standard, but few locomotives received one 4449 and 4294 had Von Bodon at the end 4460 at St Louis has one. CSRM has a digitalize set of all the SP oil burner testing reports.

The PDF versions of the report (in three sections) are available through a Southern Pacific Facebook group.

At least two of them are too large to conveniently e-mail (76.7 and 75.2MB) and I am reluctant to host them on a service like Dropbox, but I can put them on solething like a micro SD card or thumb drive if someone here needs them in that form.

May want to look at archives for other railroads than SP if you can't find SP documents. GN S-2 4-8-4s were oil burners. One example left in Havre, MT. There may be info at the Pacific Northwest Railroad Archive or other places.

For good general discussion and firebox size of different classes, general arrangements, etc, this is always a good read. It even tells you where to get your asphalt oil. Good luck, Bob.

I better get rid of this item. I could have sworn von Boden was an ATSF man. It appears he ain't.

The California State Railroad Museum library's on-line catalog returns five drawings when a search is done for "von Boden - Ingles". These are Southern Pacific drawings dating from 1916-17.

In 1912, ATSF used Booth. CP, CRIP, GN, SP & WP all used Von Boden-Ingles. What year did ATSF switch? Did they switch all to VB-I? In 1904, SP used a Sheedy until George B. Von Boden (Oil Burning Inspector) and Edwin F. Ingles (Road Foreman of Engines), both of the Southern Pacific in San Francisco, developed their burner. I don't know if it was their first, but a patent was applied for in 1911 and awarded in 1912. Von Boden (sans Ingles) patented a "conduit joint" in 1912, as well.
